MSE PRO Electrochemical Detector for Chromatography System, Model 2

MSE PRO™ Electrochemical Detector for Chromatography System, Model 2

Features

1. Advanced Noise Reduction Technology
   Utilizes an Advanced Digital Filter (ADF), distinct from the traditional Filter Time Constant (FTC), which minimizes signal loss during noise reduction. This allows low-frequency peaks to pass while eliminating high-frequency noise, improving the signal-to-noise ratio and enhancing the detection limit.

2. Innovative Analytical Flow Cell Design
   Features a central spray wall structure with continuously adjustable sensitivity. The working volume can be flexibly adjusted between 0 and 300 nL, enabling one electrode to support various sensitivity requirements.

3. Integrated Faraday-Shielded Temperature Oven
   Reduces static interference, unexplained disturbances, and the impact of temperature fluctuations, enhancing repeatability and stability.

Additional Features

• Suitable for IC, HPLC, and UHPLC systems.
• Supports DC, PULSE, and SCAN detection modes.
• Offers the highest sensitivity among electrochemical detectors.
• Compatible with different flow cells to accommodate diverse applications.
